How to check for diabetes There are three tests that check for diabetes:

1. Fasting plasma glucose test: After an 8-hour fasting period, a blood sample is drawn to check for blood glucose levels in the body. This is usually done in the morning.

Range

Diagnosis

100 mg or below
100 – 126 mg
More than 126 mg

Normal
Impaired fasting glucose
Diabetes Mellitus

2.Glucose Tolerance Test (GTT): GTT is a blood sample tested for plasma glucose also taken after an 8-hour fasting period. A specified amount of glucose dissolved in water is given to drink, and after a 2-hour break - post breakfast or lunch – a blood sample is again tested for blood glucose levels. At 120 minutes

Range

Diagnosis

Less than 140
140 – 200
More than 200

Normal
Impaired glucose tolerance
Diabetes Mellitus

3. Glycosylated Haemoglobin Estimation (HbA1c): Since glucose cells stick to haemoglobin present in blood cells, and blood cells have an average life cycle of four months before they are replaced, this test gives an average of blood sugar levels over a period of three months. This is a good tool for follow up of diagnosed diabetes patients, but not a good tool to diagnose Diabetes Mellitus.
